BOTTLE 0R BAG GASKET.

Application filed June 12, 1925'. Serial No. 36,663.

This invention relates to gaskets for use in connection with bottles orbags, being par: ticularly adaptable to the closures for hot waterbottles or ice bags.

The primary object of the invention is to provide a gasket or sealingmeans to be used upon hot water bottles or ice bags. of such characteras to be a permanent part thereof and thus obviating the possibility of.the gasket becoming detached or lost. j

A further object is to providea gasket possessing all the advantageousqualities of the now commonly used ring washer, and possessing theadditional advantage of more securely sealing the container with whichit is associated.

Still further and particular objects reside in the provision of a washeror gasket of simple and inexpensive construction, which may be easilyapplied to the neck of the container with which it is to be used, whichis so associated with the bottle or bag neck as to overcome thepossibility of accidental detachment or loss, which adds u to thegeneral appearance of the bottle or bag with which it is used, and whichwill prove highly practical and efficient in use.

IViththese objects in view, together with others which will appear asthe description proceeds, the invention consists in, the novelconstruction, combination and arrangement of parts, all as will be morefully descrlbed hereinafter, lllustrated in the drawings, and

particularly pointed out in the claim.

In the drawings:

Fig. 1 is a sectional View taken through the neck portion of an ice bagof familiar construction, and illustrating the application thereto of agasket involving the invention,

Fig. 2 is a top plan view of the ice bag with the screw cap removed, and

Fig. 3 is a transverse sectional viewtaken through the gasket per se.

As heretofore practiced, the sealing of ice or hot water bags has beenthrough the instrumentality of an ordinary rubber ring interposedbetween the outer flange of the bag neck and the cap of the container.By reason of the fact that such gaskets are independent of the cap andbottle neck, they frequently become misplaced or lost, thus renderingthe bag useless until another gasket of proper size and quality isprovided. In most instances where ice caps or hot water bags arerequired, urgency precludes the expenditure of time to find or constructa gasket which will eflectively seal the receptacle, and thereforeresort has been made to, improvised and'inefi'ective sealing mediums asasubstitute for. the proper gasket. The

use of such means has resulted in the discomfort and distress of thepatient-by reason of 5 the fact that leakage at the bottle mouthinevitably follows resort to such ineffective means. Q

It 18 the p I invention to overcome such ob ect1ons.

imary object of the presentv The gasket of my invention consists in an Hannulus or ring 4 of rubber or other similar suitable material ofa sizeto properly fit between the bottle neck and the sealing cap, and to becompressed between the latter and the said neck. This gasket hasdepending from its outer edges a skirt or apron represented at 5. Thisskirt is preferably formed integral with the gasket 4, andis of rubberor other contractile material. The skirt 5 is so formed as under normalconditions to be of substantially less diameter than the exteriorsurface of the neck of the bottle or bag, so that in applying the sameto the bottle neck it is necessary that the skirt be stretched orexpanded over the rim and held stretched by the neck of the bottle. Theskirt is thus tightly compressed and held upon the bottle neck, and thegasket connection with a bottle or bag closure employing the screwcapclosure, it is obvious that the same may be as effectively used withother types of bottle or bag closures.

It will be noted, that the apron or skirt 5 is of substantially the samedepth as the neck 7 of the bottle. In practice, the skirt and gasket maybe of the same color as the covering for the bottle vor bag, so that theneck portion and the body will be of uniform appearance. The outer edgeof the gasket passes over the flange or rim 11 and thus maintains thesame unexposed. It is preferred that the gasket portion 4 be slight- 1ythicker than the apron portion of the device, so as to possess a higherdegree of compressibility. This insures proper sealing of the bottlewhen the cap has been drawn tightly down upon the neck portion.

The gasket thus constructed and applied forms a permanent part of thebottle neck. As before stated, it is necessary that the skirt or apronbe stretched over the flange 11 and-moved downwardly until it smoothlygrips the annular face of the bottle neck. The resiliency of the skirtthus tightly main tains the device properly positioned upon the bag neckand also holds gasket portion 4 in proper position to be engaged by thecap 10. The cap may be removed in the usual manner but the gasketalwaysremains properly positioned upon the bottle neck and thus heldagainst accidental detachment or loss.

While the above is a description of the invention in its preferredembodiment, it

is apparent that slight variations therein may be made if desiredwithout departing from the spirit of the invention as defined by theclaim.

Having thus described my invention,

I claim:

The combination with a bottle neck having an outwardly projecting flangedisposed substantially at right angles to the neck and a' stopper forinsertion inthe neck and having a flat portion overlying said flange; ofa gasket comprising a flat ring of pliant material of substantially thesame breadth as said flange and adapted to lie upon the latter and to becompressed by said flat portion, a channel portion toreceive the outeredge of said bottle neck, and a skirt extending'beneath said flange;said gasket having its channel and skirt portions of slightly lessdiameter than said bottle flange and neck respectively, -whereby tosnugly embrace the latter upon its top, bottom and outer edges.

In testimony whereof I hereunto aifix my signature.
